I just picked up one pack of 25 TDK CD's from COMPUSA on Long Island, and the label said that it was manufactured in the USA. So I ran CDR Identifier on it, and it didn't show up as either Ritek or Taiyo Yuden but rather as:
Disc Manufacturer: TDK Corp.
Dye (Type No.): Cyanine (Type 0)
nominal capacity: 658.74MB
For those that are worried about cheap quality, such as the 200 for free from OfficeMax, I remember hearing that the TDK's manufactured by TDK are simply one of the best. I'd go out and grab these since they're free and great quality.
